Obviously the five families are the dominate force in LCN and historically oversaw smaller families. But what about today?

The Decavalcantes have been "under" the Gambinos for quite some time, and shared turf in Jersey leads to frequent interactions. The same goes for Philly due to the proximity to NY and turf in Jersey.

But what about outside of that? Are there any examples lately of anyone from NY and the Patriarca family interacting or sharing interests? Or to take things a step further, Chicago or Detroit? I'd find the latter hard to believe.
